Die Verbindung zwischen Netzen (Autonomen Systemen) unterschiedlicher Betreiber erfolgt sowohl durch Peering-Vereinbarung als auch über Transit-Verbindungen. Kommerzielle Transitanbieter bieten ihren Kunden Zugriff auf bzw. Erreichbarkeit für das gesamte Internet. Im Gegensatz dazu wird durch...

Myanmar has experienced a series of total and partial internet shutdowns since the military coup in February 2021. These restrictions have varied in intensity across the country and over time, ranging from the complete shutdown of all wireless broadband services and nightly shutdowns of fixed...

Recent and ongoing investments into telecommunications infrastructure have facilitated the repeated waves of digitization, both in personal and professional life. I address the question of which actors should contribute to investment costs into telecoms infrastructure and how. One widely...

Dieser Diskussionsbeitrag ist Teil der Forschungsaktivitäten des WIK zum Thema "Übergang von Kupfer- auf Glasfasernetze in Deutschland". Mit diesen Forschungsaktivitäten unterstützt das WIK die Arbeiten und Erörterungen des Gigabitforums der Bundesnetzagentur. Die Migration der Kunden auf...

Der Trend zur Digitalisierung in der Gesellschaft, Wirtschaft und in öffentlichen Institutionen in Deutschland bedingt damit einhergehend einen zunehmenden Bedarf nach leistungsfähigen Funkdiensten für vielfältige digitale Anwendungen von unterschiedlichen Nutzerkreisen. Die daraus...

The newly passed German telecommunication regulation has set the deployment and sharing conditions of in-building infrastructure with the purpose of addressing the need of generating proper incentives to network operators to invest in and extend their very high capacity access networks. At the...

African governments and the AU have supported the development of the continent’s Information and Communication Technology (ICT) sector. China, too, has increasingly invested in that sector. This Policy Brief argues that while Beijing meets Africa’s need for the development, helps bridge the...

This study aims to examine the impact of infrastructure on firm performance in nine CAREC countries: Afghanistan, Azerbaijan, Georgia, Kazakhstan, the Kyrgyz Republic, Mongolia, Pakistan, Tajikistan, and Uzbekistan. Empirical analysis is based on the enterprise survey for 2009, 2013, and 2019....

Um wettbewerbsfähig zu bleiben, muss Deutschland sich zu einer vernetzten und digi-talisierten Gesellschaft entwickeln. Dazu bedarf es einer gemeinsamen Kraftanstrengung aller beteiligten Akteure. Dies gilt insbesondere für den dringend erforderlichen Ausbau möglichst flächendeckender...

In Europe, alternative network operators have rolled out own FTTH networks in numerous regions. They often realise first mover advantages and thus dispose (at least for some time) of superior infrastructures. In comparison to copper infrastructures of incumbent operators, most alternative...

In this paper, we formulate and estimate a structural model of demand to analyse the equilibrium effect of the RAN sharing by using cross-country panel data in 28 EU countries in years 2010-2020. Based on model estimates, our simulation analysis in Spain firstly provides a quantitative...

El Proyecto Mesoamérica (PM, antes Plan Puebla Panamá) tiene como objetivo general contribuir con el proceso de integración y desarrollo de los países de la región. Su objetivo específico es conceptualizar, gestionar financiamiento, y apoyar la ejecución de propuestas y proyectos de...

The continuous increase in the complexity and the heterogeneity of corporate and healthcare telecommunications infrastructures will require new assessment methods of quality of service (QoS) provision that are capable of addressing all engineering and social issues with much faster speeds. Speed...

This paper studies the effects of infrastructure sharing agreements on telecommunications markets. Using an oligopoly model with an investment stage where firms compete " à la Cournot", I find that provided no firm is excluded, infrastructure sharing agreements decrease prices, increase...

The European Union’s digital future is counting on fast and robust development of 5G networks. However, this fast deployment of 5G networks represents, on one hand, not only brings an incentive but rather a necessity to co-operate, to share some components of this new infrastructure under the...

Is private industry investing in backbone digital technology in a manner consistent with social policy? To address this question we assemble highly disaggregate data and compute indices for the geographic distribution of advanced backbone information technology in computing and...

The regulation of telecommunications, railroads, and other network industries has been based on mandatory unbundling and facilities sharing - entrants have the option to lease part or all of incumbents' facilities if and when they desire, at rates determined by regulators. This flexibility is of...

While much economic policy presumes that more information infrastructure yields higher economic returns, little empirical work measures the magnitudes of these returns. We examine investment by local exchange telephone companies in fiber optic cable, ISDN lines and signal seven software,...

This paper addresses the impact on investment incentives of the network sharing arrangements mandated by the Telecommunications Act of 1996, with a focus on the implications of irreversible investment. Although the goal is to promote competition, the sharing rules now in place reduce incentives...

The economic growth of most sub-Saharan African countries in the past years has not been able to equalize with other regions. Even though financial development has been highlighted in several empirical literature as a factor that could spur up economic growth, the level of financial development...

It has traditionally been argued that the development of telecommunications infrastructure is dependent on the quality of countries' political institutions. We estimate the effect of political institutions on the diffusion of three telecommunications services and find it to be much smaller in...

Does internet use trigger sex crime? We use unique Norwegian data on crime and internet adoption to shed light on this question. A public program with limited funding rolled out broadband access points in 2000–2008, and provides plausibly exogenous variation in internet use. Our instrumental...

Die Debatte um den Ausbau von Mobilfunk- und Glasfasernetzen in Deutschland bedarf einer Objektivierung. Statt Ängste zu schüren, gilt es nüchtern zu überprüfen, ob die Privatisierung der physischen Infrastruktur vor rund 25 Jahren sowie die getrennte Betrachtung von Glasfaser- und...

Purpose The main purpose of the present study was to improve and develop previously proposed models for Iran telecommunication networks. It should be noted that the six-dimensional (6D) sustainability model used in this study will be a useful and comprehensive model for industries. Since, the...

Data and connectivity platforms play a key role in the digitalization of different sectors of our society. The availability of new services that are specialized to the needs of a given vertical sector in a specific location can significantly boost the business opportunities of that ecosystem. 5G...

Horizontal ownership concentration and its consequences is an extraordinarily important contemporary topic. Yet, outcomes evidence is slim. Based on historical data, this retrospective analysis has assessed the impact of horizontal acquisitions on communications infrastructure investment, using...

The recent deployment of fibre-optic submarine cables (SMCs) in sub-Saharan Africa (SSA) raised the prospects for the digital economy expansion and the whole sub-continent take-off, but also exposed countries and populations to new sources of vulnerability. This paper provides empirical evidence...
